Title: A telephone system with sub-exchange
IPC: H04Q3/58
Filed: 1961-11-22
Abstract: 1,004,090. Automatic exchange systems. TELEFUNKEN. Nov. 22, 1961 [Nov. 26, 1960], No. 41776/61. Heading H4K. In a system in which switches at an exchange and at a concentrator are set to the same position dependent on the subscriber concerned, a signal identifying the subscriber is sent twice over the exchange line, the first time in the direction of the call, and the connection is established only if the two signals are identical. The signals may be sent in binary code form. Four alternatives arise for the second signal. It may be sent (1) in the same direction as the first, (2) in the reverse direction, (3) always from exchange to the concentrator, or (4) always from the concentrator to the exchange. In case (1), a preliminary seizing signal is necessary to avoid simultaneous sending of an identifying signal from both ends. In cases (1) and (4), since the comparison of signals on a call from the concentrator is made at the exchange, a subscriber barred from making outgoing calls is disabled by a signal from the exchange. In all cases a pilot tone may be employed to indicate when the connection has been made at the concentrator.

Title: Lockable castors
IPC: B60B33/02
Filed: 1973-09-06
Abstract: 1439500 Lockable castors TENTE-ROLLEN GmbH & CO 6 Sept 1973 [3 March 1973] 41983/73 Heading A4V A castor has a wheel 1, Fig. 3, mounted in a fork 3 and a brake lever 4 pivoted at 7 on the fork, one arm 4a of the lever carrying a bolt 17, for braking the wheel 1, and a push-button 5 having a pin 14 engaging a spring-loaded locking member 6 which is pivoted on the arm 4a, and the other arm 4b of the lever engaging a leaf-spring 15 having noses 15a which are engageable with a stationary member 16 to lock the fork against swivelling. The push-button 5 has an operation similar to that of a ball point pen whereby when the button is pressed by foot the lever 4 moves to brake the wheel and lock the fork, and depression of the part 13 in its housing extends the pin 14 to pivot the locking member 6 to a position in which its arm 6b is moved out of alignment with an aperture 9 in the fork 3 into engagement with the fork to hold the lever 4 in its braking position, Fig. 4 (not shown). A second application of foot pressure on the push-button releases the pin 14 and so permits the locking member 6 to return to its unlocking position and the lever to its non- braking position. The push-button 5, Figs 5 to 8 (not shown), operates with a toothed rotary disc having only four indexing teeth. In a second embodiment, Fig.9, and Fig. 10 to 20 (not shown) the push-button has a housing 21 having internal grooves 36, and indexing-teeth 37 between which are spline grooves (38) of lesser depth than the grooves 36. A spring-loaded member 24 is slidably mounted in the housing 21 having indexing-teeth 41 alternatively engageable in the grooves 38 and 36, and a toothed disc 35 is rotatably mounted in the housing 21, its teeth 43 being constructed as upwardly orientated indexing-teeth for co-operation with the indexing-teeth 41 of the member 24, as well as with the indexing teeth 37. In operation repeated depression of the member 24 indexes the disc 35 to alternately engage its teeth 43 in the grooves 38 and 36 to lock the disc in its extended position or release it for return upward movement.

Abstract: 1,014,210. Packages. TETRA A.B. Oct. 16, 1964 [Nov. 9, 1963], No. 42336/64. Heading B8C. A package is formed from a paper web 1 having a cut line 7, the web being coated on one of its surfaces with an extruded plastics film, e.g. of polyethylene, and a heated tool applied to an area 6 of the web to cause the plastics material to oxidize and the web in that area to become brittle; at the same time the film is made more adherent to the web in the area 6. The web is then formed into a tube by uniting its edges 2, 3, and the tube is sealed at intervals after material is filled into it. The tube is mechanically deformed to the parallelepipedic shape of Fig. 2, and it is sealed so that the edge 10 of the fin 9 corresponds to an interrupted line 11 on the blank. The fin is torn along the line 7 to open the package. The package may be non-rectilinear or of tetrahedran shape.

Title: Method and apparatus for welding metal elements to curved surfaces
IPC: F28F1/36
Filed: 1961-11-27
Abstract: 933,848. Making finned tubes; welding by pressure; coiling. AMERICAN MACHINE & FOUNDRY CO. Nov. 27, 1961 [Feb. 23, 1961], No. 42353/61. Classes 83 (2) and 83 (4). In welding a narrow elongated surface portion of a metal member to an advancing metal surface which curves away from the direction of advance of the member in its approach to the surface after passing the weld point, a current of at least 50 kc. per sec. is caused to flow between points on the member and surface in advance of the weld point where the member and surface come into contact, the current being applied to a point on the member opposite the surface portion thereof which contacts the surface to flow across the member and being such as to anneal the member to allow it to be readily stretched and bent during its application to the surface. The member may be a strip, rod or tube. Metal strip 11a, Fig. 2, is pulled on to a tube section 10, rotated and advanced by skew rollers 14, to form a helical fin 11 and electrode 30, 31 supplied with current of up to 450 kc. per sec. are applied to the tube surface and the upper edge 26a of the strip so that current flows along path 36 across the strip to the weld point w, the strip being guided and pressed on to the tube at this point by grooved roller 25, the lower edge of the strip and the tube surface are heated to welding temperature at point w and the upper edge of the strip is softened and allowed to stretch with some reduction in thickness of the upper edge, during winding. Guide rollers 16 for the tube are provided between turns of the fin. Separate pipe sections such as 13 are rotated and advanced by rollers 18 at a speed which tends to be slightly faster than section 10 to push section 10 through the welding region. When the trailing end of section 10 approaches the welding region welding current is cut off so that one or more turns of unwelded fin are applied to the ends of adjacent sections, the fin being severed as at 23 after spacing, e.g. manually, the adjacent tube sections. The parts may be of steel, aluminium or copper and a solid or hollow rod-like member may be used for the fin. Water or oil may be applied for cooling the weld point. Specification 853,673 is referred to.

[Also in Group XL (c)] A radio apparatus for insertion within a living body to transmit information relating to temperature, pressure or pH to a receiver outside has its power supply provided by radio-frequency signals from a source external to the body. The radiofrequency power is transmitted as pulses, at a frequency equal to the resonant frequency of the circuit 2, 4, in the internal apparatus, is applied to the base and collector of a transistor 1 and rectified to charge a capacitor 7. During this period a capacitor 5 is also charged. When the incoming pulse stops, the circuit operates as a Hartley oscillator at a frequency determined by the circuit 2, 4 and oscillations continue until the capacitor 7 is discharged. A separate rectifier and tuned circuit may be provided for the power supply. A variation of the time constant of the circuit 5, 6 which varies the delay between the end of the power supply pulse and the start of the information pulse, or varies the number of pulse trains transmitted, may be used to transmit the required information, or alternatively the resonant frequency of the circuit 2, 4 may be varied. A Zener diode may be connected across the capacitor 7. It is suggested that a tunnel diode may be used instead of a transistor. The resistor 6 may be replaced by a thermistor to transmit temperature or the capacitors 4 or 5 may be temperature-sensitive. Alternatively, the ferrite core 3 may be of the type which provides a large variation of permeability with temperature. A diaphragm may be arranged to move the core 3 in response to internal pressure, and the measurement of pH may be achieved by means of a plastic body which is attached to the core 3 and varies its dimensions in dependence on the pH value.
